15 Mar 2010TL;DR: A complete radar transceiver for 77 GHz with two integrated antenna elements is presented, which exhibits a well defined antenna pattern with an efficiency of better than 50%.
Abstract: A complete radar transceiver for 77 GHz with two integrated antenna elements is presented. Based on a previously published design [1], two of the transmit and receive channels of the transceiver are supplemented with integrated antenna elements. The antennas exhibit a well defined antenna pattern with an efficiency of better than 50%.

TL;DR: In this article, a single chip, dual-functionality radio and FMCW radar transceiver operating at 140 GHz is described, and the measured receiver noise figure, gain, and phase noise are 7.5 dB, 20 dB, and −100 dBc/Hz@1MHz offset, respectively.
Abstract: A single chip, dual-functionality radio and FMCW radar transceiver, operating at 140 GHz is described. Doppler, loop-back, and 4Gb/s NLOS radio link demos, over the air and at distances exceeding one meter, are demonstrated. The second part of the paper presents novel, sub-1.8 V circuit topologies intended for a low power, high resolution 120 GHz radar transceiver with self-calibration capabilities. The measured receiver noise figure, gain, and phase noise are 7.5 dB, 20 dB, and −100 dBc/Hz@1MHz offset, respectively.

TL;DR: An approach is presented in which the computational complexity is significantly reduced by using scattering center models for the most complex objects, designed to study deterministically the wave propagation for vehicle based radar systems operating near 80 GHz.
Abstract: Deterministic radio channel simulations for large and complex environments at very high frequencies are a challenging task. In this paper an approach is presented in which the computational complexity is significantly reduced by using scattering center models for the most complex objects. The scattering centers are described in form of directional, bistatic scattering intensities and can be computed for the isolated complex object in advance without considering the complete environment. Thus, the simulation performance benefit is due to a significant reduction of the complexity of the geometrical representation of the scene. The parameterization of the scattering centers itself is based on an efficient high frequency asymptotic field prediction tool incorporating Geometrical Optics and other techniques. The models are designed to study deterministically the wave propagation for vehicle based radar systems operating near 80 GHz. An example for a bistatic three-dimensional parameterization is given. Furthermore, a fast Inverse Synthetic Aperture Radar (ISAR) imaging technique is applied that can be used to find the most relevant scattering center positions on the objects.

29 Sep 2010TL;DR: In this paper, an elongated measuring waveguide (50) is provided in the base to guide an electromagnetic wave, and is moved along the path, and a jamming unit (22) i.e. electrical oscillating circuit, where the armature controls the electromagnetic wave in the measuring wave, such that the wave is reflected in a region of the jamming units.
Abstract: The apparatus (10a) has an armature movably guided along a predetermined path in a base (30). An elongated measuring waveguide (50) is provided in the base to guide an electromagnetic wave, and is moved along the path. A jamming unit (22) i.e. electrical oscillating circuit, is provided in the armature, where the armature controls the electromagnetic wave in the measuring waveguide such that the wave is reflected in a region of the jamming unit. The measuring waveguide includes two elongated electrical conductors (51, 52) separated from each other during interconnection of a dielectric (54).
